Answer:

Step-by-step explanation:

It is not A because you can say 1 - 2 and those numbers are both positive and your answer for that would be -1 which is a negative number.

You know its B because say -7 + -7 which is -14 so any negative number plus any other negative number results would also be a negative number.

Answer:

The given congruence is false.

Step-by-step explanation:

Given : Expression $12 \equiv 10 \mod 5$

To find : Determine whether the congruence is true or false ?

Solution :

The congruence is in the form $x\mod y\equiv r$

where, x is the dividend

y is divisor

r is the remainder

So, We find $10 \mod 5$

We know, 10 is completely divide by 5 and we get quotient is 2 and remainder is 0.

$10 \mod 5=0$

As $0\neq 12$

Therefore, The given congruence is false.
